PUNCHING-MACHINE.

Specification of Letters Patent.

Patented Mar. 20, 191 7.

To all whom zt may concern.'

Be it known thatL'I-IENRY LEFEBVRE, a citizen of the United States ofAmerica, residing at Douglas, in the county of Cochise and State ofArizona, have invented certain new and useful Improvements in Punching-Machines, of which the following is a specication, reference being hadtherein to the accompanying drawing.

This invention relates to punching machines and has for its object theproduction of a simple and eicient punching machine for facilitating thekeeping of the twyers open to permit the airV to pass freely into theconverter while the machine is in operation.

Another object of this invention is the production of a simple andeicient-punching device which may be easily and conveniently attached toa smelter so as to permit the punching bars to pass through the twyersand efficiently operate to keep the twyers free from obstruction.

With these and other objects in view, this invention consists of certainnovel combinations, constructions, and arrangements of i parts, as willbe hereinafter fully described andl claimed.

In the accompanying drawings Figure 1 is a top plan view of the appa'ratus.

Fig. 2 is a side elevation thereof.

Fig. 3 is an end elevation.

Fig. 4 is a longitudinal section taken on line 4 4 of Fig. 1.

Fig. 5 is a section taken on line 5-5 of Fi F ig. A6 is a horizontalsection through a portion of theconverter, showing the manner in whichthe punching bars extend therethrough. n

Fig. 7 is a horizontal section through one of the plunger cylinders,showing the manner in which the same is supported upon the supportingframework.

Fig. 8 is a transverse section through the frame and bar for supportingthe punching bars.

.Fig 9 is a section taken lon line 9 9 of Fig. 8.

Fig. 10 is a vertical section through one of the punching barssupporting members, showing the manner inwhich the punching bars aresecured thereto.

Fig. 11 is a detailed perspective of one end of the punching frame.

Fig. 12 is a transverse sectional view through the inner end of thepunching frame, showing the manner in which the same is secured to theconverter.

' Fig. 13 is a section taken on line X-X of Fig. 10.

Referring to the accompanying drawings by numerals it will be seen that1 designates the converter which is supported upon the concrete or othersuitable support 2. The converter 1 is adapted to be operated by mea-nsof a motor 3 carrying a driving sha-ft 4, which shaft 4 isprovided witha worm screw l5 meshing with a worm wheel 6. The worm wheel 6 is carriedby a shaft 7, the shaft 7 carrying supporting rollers 8 as clearly shownin Fig. 2. Other idle rollers 9 aresupported upon the base or support 2forpthe purpose of supporting the converter l, above described.y'lfhe'wheels or rollers 8 and 9 engage the supporting wheels 10 as`illustrated clearly in Fig. 2.

The converterl isprovided with the usual twyers 11 as illustrated inFig. 4, through which twyers 11 are adapted to extend the punching bars12 and 37. TheA usual wind box 13 is employed and communicates with thetwyers 11 by means of'a communicating passage 14, as illustrated in Fig.4.

The frame 15 is supported upon one side of the converter and is providedwith a pair of side portionsor rails 16 of a channel iron construction,each rail 16 carrying at its rear end a block 17, which block supportsan overhanging plate* 18 which is securely held in engagement with `theblock 17 by means of a bolt 19. This plate 18 is adapted to firmly clampover the .transversely eX- tending supporting bar 2O of the converterfor supporting the inner end of the frame 15 in engagement with theconverter. 1t should be understood that the frame may be easily andconveniently removed from the converter 1 when so desired by means ofreleasing the plates 18 from the supporting bar 20 and detaching theturn-buckle supporting mechanism hereinafter described.

The forward ends of the frame 15 are arranged in converging relation,over which ends lit the radiating arms 21 of the operating cylinders 22.These arms 21 are provided with rearwardly extending ears 23 for fittingin iirm engagement with the frame 15, the ears 23 being secured to theframe 15 by means of the rivets 24.

Two or' these cylinders 22 are employed, one cylinder being placed abovethe other, as illustrated in Fig. 4 of the drawings and a piston 25 isplaced within each cylinder which piston engages piston rods 26 and 26as illustrated in Fig. 4. The outer ends of the cylinders 22 are closedby means of the cylinder heads 27, illustrated in Fig. 4 of thedrawings. Communicating pipes 28 are connected to a suitable source ofair or water supply for supplying suitable driving power to thecylinders 22 for operating the piston heads 25. The pipes 28 communicatewith the respective ends of the cylinders to control the admission anddischarge of water or air from the cylinders 22.

1t should be understood that any suitable driving power may be employedfor the purpose of operating the piston rods 26, without departing fromthe spirit of the invention.

The frame 15 is provided upon each side thereof with an eye 29 and aturn-buckle rod 30 engages each eye 29, the upper end of eachturn-buckle rod 30 being provided with a hook 31 for engaging the eyes32 formed upon the converter 1. It will therefore be seen that theseturn-buckle rods 30 will constitute an efiicient support or brace forthe frame 15 and when it is desired, the frame may be readily releasedfrom the converter by detaching the plates 18, as above described, andalso the turn-buckle rods 30 for moving the frame 15 out of engagementwith the converter 1, thereby permitting the converter to be operatedwithout being interfered with by the punching machine.

The frame 15 is provided upon one face thereof with an upper track 33and a lower track 32. rlhe upper piston rod 26 engages a plurality ofears 34, which ears are carried by a transversely extending bar 35having its ends traveling in the track 33. A plurality of heads 36 aresuspended below the upper bar 35 and a punching rod 37 is supported uponeach head 36, being firmly held in engagement therewith by means of theclamping bolts 38. The heads 36 are held in detachable engagement withthe bar 35 by means of the nuts 39 which are threaded upon the bolts 40of the heads 36. The punching bars 12 pass through the guides 41 carriedby the supporting plate 42 of the converter frame so as to guide thepunching bars 12 through the twyers 11 as above described for keepingthe twyers clean and tree to permit the air to freely pass therethroughwhile the machine is-in operation.

The lower piston rod 26 is secured at its outer end to a transverselyextendingbar 43 which supports a plurality of heads 44 to which headsare secured the punching bars 12, as clearly shown in Fig. 4. Thesepunchingbars 12 pass through the guides 41 carried by the converter 1,the guides of the lower punching bars being arranged in staggeredrelation with respect to the guides for the upper punching rod. Thetransversely extending bar 43 travels in the lower track 33 as clearlyillustrated.

It is necessary to employ different series of punching rods in .order toprevent too much air coming out of the converter at one time, for thereason that air is bound to esvcape during the punching operation. 1t ofcourse is obvious, that if all the rods were operated at one time,hardly any air would pass through the converter, while in operation.Therefore, by punching one half o`f the rods at a time, about one halfof the blast is effective.

What I claim is 1. A punching device of the class described comprising aframe, said frame provided with an upper and a lower track, atransversely extending bar working in each track, a series of punchingbars supported upon each transversely extending bar, each set ofpunching bars being arranged in staggered relation, and means forreciprocating said punching rods upon said frame.

2. A punching machine of the class described comprising a frame, anupper and lower track, a transversely extending bar secured to eachtrack, punching rods secured to each transversely` extending bar, thebars carried by the upper and lower transversely extending bars beingarranged in alternate spaced relation, means for reciprocating saidtransversely extending bars upon said track, and guiding means fordirecting said punching bars into the converter.

3. In combination with a converter provided with twyers, of a frame, aplurality of tracks carried by said frame, a transversely extending barworking in each track, punching bars secured to each transverselyextending bar, and said bars working alternately with respect to eachother for causing one half of the air blast to remain eiective duringoperation.

4. In combination with a converter provided with twyers, of a frame, aplurality of tracks carried by said frame, a transversely extending barWorking in each track, punching bars secured to each transverselyextending bar, punching bars carried by one transversely extending barfitting between the'punching bars of the other transversely extendingbar, and means for alternately reciprocating the different series ofpunching bars for causing at least one half of the air blast to remaineeotive during operation.

In testimony whereof I hereunto aHiX my signature.
